Vincent *knew* my program since he plays it on ICC all the time, and he *knew* that the parallel search was going to give him problems because it is a quick and dirty 2X speed boost when someone uses it on a dual. He asked me to look, saying "I don't mind losing to 'crafty'... but I do mind using to a program that claims to be far different, but which really isn't based on my trying the moves in the game." I was sympathetic to him, Marcel, and others that were communicating with me. Had I wanted Crafty in that tournament, *I* would have entered it. I'd claim that so long as any significant part of my source code is used in a program, I am definitely co-author of that program. That seems to get overlooked here...
